The Impact of digital X-ray with Teleradiology on Case Management in Mweso, Democratic Republic of CongoKosack, Cara; Halton, Jarred; Greig, Jane; Shanks, Leslie; Spijker, Saskia; MSF-OCA (2018-07)Study objectives 3.1 Primary objective To demonstrate the extent of change in patient management through the availability of digital X-ray with teleradiology consultation. 3.2 Secondary objectives a) To demonstrate the extent of change in patient diagnosis through the availability of digital X-ray with teleradiology consultation. b) To demonstrate the extent of change in patient diagnosis and management in the subgroup of patients with chest pathologies through the availability of digital X-ray with teleradiology consultation. c) To estimate if the extent of change in diagnosis and management is different in patients < 5 years of age versus ≥5 years of age.
Multi-site evaluation of HIV testing algorithmsKosack, Cara; Page, Anne-Laure; Shanks, Leslie; Chaillet, Pascale; Beelaert, Greet; Fransen, Katrien; Benson, Tumwesigye T.; Savane, Aboubacar; Nganga, Anne; MSF-OCA (2018-07)Objectives 3.1 Primary objective To evaluate the overall and site-specific performance of the diagnostic algorithm performed at 6 MSF African program sites (i.e. using RDT results from the program sites) comparing using the diagnostic algorithm with ELISA, LIA, EIA-Ag and DNA-PCR as gold standard. 3.2 Secondary objectives To evaluate the accuracy (sensitivity, specificity and predictive values) of Orgenics ImmunoComb® II HIV 1&2 Combfirm as an HIV confirmatory test. To model different HIV RDT testing algorithms in order to define acceptable testing algorithm in each study setting (i.e. using RDT results from reference laboratory). To determine the inter-user reliability of RDT testing (i.e. program sites vs. reference laboratory) To evaluate accuracy of each HIV RDT measured by the sensitivity (SN), specificity (SP) and predictive values based on the prevalence of each testing centre. To evaluate the accuracy of HIV testing using DPS samples for quality control purpose in HIV testing. To assess whether additional confirmatory testing (i.e. Orgenics ImmunoComb® II HIV 1&2 Combfirm) improves the accuracy of the diagnostic algorithm used at the different study sites. To perform a descriptive analysis on the differentiation between HIV 1 and 2 of the discriminative RDTs.
